Wanna make a good first-time impression at your dream engineering job? Try this PCB business card that can be converted into a USB flash drive!
The main purpose of the card is to work as an USB memory.
The firmware uses the internal flash of the microcontroller, so the capacity of the mass storage unit is only 24 KB max. Enough to put a cover letter and resume in HTML.
If more memory is needed, the current PCB and circuitry supports an external 8-pin SPI (or I2C) flash memory chip (up to 32MB!). Interesting for providing the project documentation or code!
